Environment

  • Use nix run for missing commands and --quiet for Nix commands.
  • Capture large Nix listings in /tmp; read targeted excerpts and failure logs. Locate store files before reading them.
  • Manage persistent binaries, skills, plugins and MCP definitions in /home/kiri/.config/nixos. Keep interactive settings, credentials and session state outside Nix.

Work

  • Complete authorized work without repeated confirmation. Make reasonable assumptions for routine choices; ask about consequential unknowns while continuing independent work.
  • Prefer existing capabilities and simple solutions. Add abstractions or compatibility code only for a concrete need; explain required manual steps.
  • Verify unfamiliar or consequential APIs against version-appropriate primary documentation; prefer Context7.
  • Never push without my explicit approval. Other remote actions must remain within the authorized task.
  • User instructions take precedence over skill guidelines, including testing defaults.

Validation

  • Write or run automated tests only when explicitly requested or covered by the repository's established testing policy. Do not invent a testing policy or introduce tests into a repository without tests unless explicitly requested.
  • Validate changes with the smallest relevant build, manual behaviour check, or review of code and output.
  • Broaden or repeat validation only for changes, failures or unresolved concerns. Report only checks performed.

Writing

  • Lead with the result. Write concisely in plain language, preserving important reasoning, evidence and limitations.
  • Omit repetition and stock phrases. Use lists when they improve readability.
